From 4e0c04ec3a304490a83d5c0355e64176acc9b4ba Mon Sep 17 00:00:00 2001 From: Guoju Fang Date: Thu, 25 Apr 2019 00:48:27 +0800 Subject: [PATCH] bcache: fix inaccurate result of unused buckets To get the amount of unused buckets in sysfs_priority_stats, the code count the buckets which GC_SECTORS_USED is zero. It's correct and should not be overwritten by the count of buckets which prio is zero.
